So i am confused here what really works after 4-5 year when time to r&r the
exhaust again

I tried some 304 ss 12 mths ago for the tail pipe connected to the muffler
with anti-seize
( the 1800F copper stuff)
so for shits & giggle when my connector pipe went the other day I thought
I'd see how easy
the 3 304 ss bolts come off well they wont come off.. well really easy any
ways with a socket wrench
so I guess I have what they call galling occurring when the ss has heated up
& come off & bonded to the steel
thread in the muffler...

So now when i do the connector pipe what grade of ss do i use 304 is out so
3XX or zinc plated ??
I will try the 2400F nickle based anti-seize
